The Meteorology Research, Inc. MRI Total Water Content Instrument TWCI is an aircraft-mounted sampler for near real-time mass measurements of ice and water drops in the atmosphere. Its high volume sampling rate of 39 cu m per minute assures a representative sample. Hydrometeors are collected on an impaction surface that is continually washed with a flow of silicone fluid. The fluid carries the sample through a capacitance detector cell. Changes in capacitance are directly proportional to the water fraction in the cell. Performance comparisons were made between the TWCI and the Particle Measurement Systems PMS optical instruments. These comparisons included flight testing aboard a Piper Navajo aircraft. Author
